FILE NO. 810-200019 SERVICE MANUAL DVD VIDEO PLAYER SD-2300 Feb., 2001 5 LASER BEAM CAUTION LABEL When the power supply is being turned on, you may not remove this laser cautions label. If it removes, radiation of a laser may be recceived. PREPARATION OF SERVICING Pickup Head consists of a laser diode that is very susceptible to external static electricity. Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement, its life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire, etc. to protect the laser diode from damage by static electricity. And also, the LSI and IC are same as above. Ground conductive wrist strap for body. Soldering iron with ground wire or ceramic type 1M Conductive mat The ground resistance between the ground line and the ground is less than 10. SAFETY NOTICE SAFETY PRECAUTIONS LEAKAGE CURRENT CHECK Plug the AC line cord directly into a 120V AC outlet (do Measure the AC voltage across the 1500 resistor. not use an isolation transformer for this check).
